The energy-storage-focused venture fund Volta Energy Technologies added two strategic backers, bringing total funds raised to $180 million. The Norwegian energy major Equinor (formerly Statoil) and automotive equipment vendor Hanon Systems joined previous investors Exelon and Albemarle. Based in Chicago, Volta aims to speed up commercialization of energy technologies through close collaboration with Argonne National Lab and strategic investors who can put the products to work. The fund will disburse its money over the next five to seven years, at a likely pace of four to seven investments per year, CEO Jeff Chamberlain said via email.
